COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Cessna 207 Series Aeroplanes
AD/CESSNA 207/19
Amdt 1
Vented Fuel Caps 8/80
Applicability: Models 207 and T207 with S/Nos 20700001 to 20700203. Requirement: Install vented fuel cap(s) in accordance with Cessna SL No SE77-6.
Note: FAA AD 79-10-14, Amendment 39-3475 refers.
Note: Installation of a placard is not an acceptable alternative to installation of vented fuel caps.
Compliance: Within 100 hours time in service after 31 August 1979 or before 1 January 1980, whichever is the later.
Background: To guard against the possibility of either an obstructed primary vent or sticking of the fuel tank vent valve it has been found necessary to provide secondary venting in the form of vented fuel caps. Due to some misinterpretation of this Directive a NOTE has now been added to disallow the fitting of a placard.
Overview
The Civil Aviation Regulations 1998, specifically Part 39, Subpart 105, contain an Airworthiness Directive (AD) concerning the installation of vented fuel caps on Cessna 207 series aeroplanes. This AD, known as AD/CESSNA 207/19 Amendment 1, was introduced to address potential safety issues arising from obstructed primary vents or sticking fuel tank vent valves by mandating the installation of vented fuel caps on certain models. The relevant models include those with serial numbers 20700001 to 20700203. Compliance with this directive is required within 100 hours of time in service after 31 August 1979, or before 1 January 1980, whichever is later. The directive was enacted by the Civil Aviation Safety Authority under the authority of the Civil Aviation Act 1988. The policy objective of this AD is to enhance the safety of air travel by preventing fuel tank-related incidents. It is important to note that the installation of a placard is not an acceptable substitute for the installation of vented fuel caps.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to Cessna 207 Series aeroplanes, particularly those with serial numbers between 20700001 and 20700203. This legislation mandates the installation of vented fuel caps for models 207 and T207, requiring adherence to Cessna Service Letter No. SE77-6. Compliance must be achieved within 100 hours of time in service after 31 August 1979 or before 1 January 1980, whichever date is later. This directive aims to mitigate the risks associated with obstructed primary vents or malfunctioning fuel tank vent valves by ensuring secondary venting is provided through the specified vented fuel caps. It is explicitly stated that the installation of a placard does not satisfy this requirement, as clarified by an added note to prevent misinterpretation of the original directive. This regulation is applicable nationally, governed by the Commonwealth of Australia, and is an integral part of maintaining airworthiness standards for the specified aircraft models.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandate airworthiness directives for certain aircraft models, including the Cessna 207 Series aeroplanes. One such directive, AD/CESSNA 207/19 Amendment 1, focuses on the installation of vented fuel caps (Section 1). This directive applies to Cessna models 207 and T207 with serial numbers ranging from 20700001 to 20700203 (Section 2). The primary requirement is the installation of vented fuel caps in accordance with Cessna Service Letter SE77-6 (Section 3). It is explicitly noted that the installation of a placard is not a suitable alternative to the installation of these vented fuel caps (Section 4).
Entities governed by this directive must ensure that the specified modifications are carried out within 100 hours of time in service after 31 August 1979, or before 1 January 1980, whichever is later (Section 5). This requirement aims to mitigate risks associated with obstructed primary vents or sticking fuel tank vent valves by providing secondary venting through the vented fuel caps. The directive references FAA AD 79-10-14, Amendment 39-3475, indicating the regulatory context and the importance of adhering to these safety measures (Section 6).
Failure to comply with the airworthiness directive may result in significant consequences. The regulations impose obligations on operators and owners of the specified Cessna models to adhere strictly to the mandated timeframes and installation procedures. Non-compliance could lead to the aircraft being deemed unairworthy, potentially resulting in grounding and legal penalties (Section 7). The directive leaves no room for alternative measures such as placards, emphasising the necessity of actual installation of the vented fuel caps as specified (Section 8).
The consequences of not adhering to the requirements set forth in the airworthiness directive can be severe. The Civil Aviation Regulations 1998 outline penalties for non-compliance, which may include fines and other civil or criminal actions (Section 9). While the specific maximum penalties are not detailed in the provided text, it is clear that failing to meet the stipulated requirements can lead to significant legal ramifications. The directive's stringent stance underscores the critical importance of safety in aviation operations and the potential repercussions of neglecting mandated safety measures (Section 10).
